No. Just no. Your entitled to your opinion, and if you want to just play as a Titan or Hunter, by all means go for it. But Warlocks are more than able to carry 2 grenades without an armor perk, you just have to level up your Sunsinger subclass. Plus, there is armor that allows you to carry more heavy and special ammo. Said armor might be RNG based in loot drops, and you might have to sacrifice a virgin to the gods of RNG to get it, but those pieces are available. All classes have their strengths and weaknesses, but for the most part, they are very comparable. It's not like most RPGs where you have dedicated Tank, DPS, and Healer roles. All classes are comparable.
